Netflix needs to report across all this data, but given the scale involved this is a nontrivial challenge. Its approach is to use Hadoop that uses SSTable backup as the source of its jobs. In the end, Netflix ended up implementing a pipeline capable of processing large amounts of data using this approach, which it then open sourced as the Aegisthus project. Like data pumps, though, with this pattern we still have a coupling to the destination reporting schema (or target system).
